Dead Coral Blocks

In Minecraft, dead coral blocks are the gray variants of living coral blocks, and they come in five types: tube, brain, bubble, fire, and horn. These blocks are always gray and cannot be revived by any means. They can be obtained in several ways: by mining them with any type of pickaxe, or by mining living coral blocks with a pickaxe that does not have the "Silk Touch" enchantment. Dead coral blocks generate naturally in coral reef structures in warm oceans (Bedrock Edition only), while they do not generate naturally in Java Edition. Unlike living coral blocks, dead coral blocks cannot be used for farming sea pickles, but they can be used as building or decoration materials. All types of dead coral blocks can be placed under note blocks to produce "bass drum" sounds.
